Caution1. Remove dusts or drain before piping. They may get into the peripheral

machine / facilities and cause malfunction.2. When inserting an ultra-soft tube into push-in fitting, make sure to place

an Insert Ring into the tube edge. There is a risk of causing the escape of tube and a fluid leakage without using an Insert Ring.

3. The product incorporating NBR as seal rubber material has a risk of malfunction caused by ozone crack. Ozone exists in high concentrations in static elimination air, clean-room, and near the high-voltage motors, etc. As a countermeasure, material change from NBR to HNBR or FKM is necessary. Consult with PISCO for more information.

4. Special option “Oil-free” products may cause a very small amount of a fluid leakage. When a fluid medium is liquid or the products are required to be used in harsh environments, contact us for further information.

5. In case of using non-PISCO brand tubes, make sure the tolerance of the outer tube diameter is within the limits of Table 1.

　●Table 1. Tube O.D. Tolerancemm size Nylon tube Polyurethane tube inch size Nylon tube Polyurethane tubeø1.8mm ─ ±0.05mm ø1/8 ±0.1mm ±0.15mmø3mm ─ ±0.15mm ø5/32 ±0.1mm ±0.15mmø4mm ±0.1mm ±0.15mm ø3/16 ±0.1mm ±0.15mmø6mm ±0.1mm ±0.15mm ø1/4 ±0.1mm ±0.15mmø8mm ±0.1mm ±0.15mm ø5/16 ±0.1mm ±0.15mmø10mm ±0.1mm ±0.15mm ø3/8 ±0.1mm ±0.15mmø12mm ±0.1mm ±0.15mm ø1/2 ±0.1mm ±0.15mmø16mm ±0.1mm ±0.15mm ø5/8 ±0.1mm ±0.15mm

6. Instructions for Tube Insertion① Make sure that the cut end surface of the tube is at right angle without

a scratch on the surface and deformations.② When inserting a tube, the tube needs to be inserted fully into the push-

in fitting until the tubing edge touches the tube end of the fitting as shown in the figure below. Otherwise, there is a risk of leakage.

Tube end

Sealing

Tube is not fully inserted up to tube end.

③ After inserting the tube, make sure it is inserted properly and not to be disconnected by pulling it moderately.

※. When inserting tubes, Lock-claws may be hardly visible in the hole, observed from the front face of the release-ring. But it does not mean the tube will surely escape. Major causes of the tube escape are the followings; ①Shear drop of the lock-claws edge②The problem of tube diameter (usually small)Therefore, follow the above instructions from ① to ③, even lock-claws is hardly visible.

21

7. Instructions for Tube Disconnection① Make sure there is no air pressure inside of the tube, before disconnecting it.② Push the release-ring of the push-in fitting evenly and deeply enough to

pull out the tube toward oneself. By insufficient pushing of the release-ring, the tube may not be pulled out or damaged by scratch, and tube shavings may remain inside of the fitting, which may cause the leakage later.

8. Instructions for Installing a fitting① When installing a fitting, use proper tools to tighten a hexagonal-column

or an inner hexagonal socket. When inserting a hex key into the inner hexagonal socket of the fitting, be careful so that the tool does not touch lock-claws. The deformation of lock-claws may result in a poor performance of systems or an escape of the tube.

② Refer to Table 2 which shows the recommended tightening torque. Do not exceed these limits to tighten a thread. Excessive tightening may break the thread part or deform the gasket and cause a fluid leakage. Tightening thread with tightening torque lower than these limits may cause a loosened thread or a fluid leakage.

③ Adjust the tube direction while tightening thread within these limits, since some PISCO products are not rotatable after the installation.
